5 tral portion of the w UNITED sTATEs PATENT OFFICE. I ROBERTF. PHILLIPS, or GARRICK; imnnsrnvAmA. I SELF-OILING CAR-WHEEL.-

5 gheny and State of Penns lv'ania, have invented certain new and use lIm' rovements in Self-oiling Car-Wheels, of which the fol lowing is a specification,-reference being had therein to the accompanying rawings'.

[0 My invention has relation to car-wheels,

and es ecially .to that ;t wheels own astspring-o' oil-chamber surrounding the hub of the wheel is rovided with a spring-valve which e of mine-car closes a" ole in the side of the wheel and which may be pressed inwardly by means of the nozzle of the oil-can to'admit asupply of oil to the chamber. a

4 ,The objectof my invention is to provide 2o novel means for oiling car-wheels and axles provided'with spring-oilers, whereby the insertion and fitting of the oiling-valve and spring within'the oil-cavity is facilitated and certain ob'ectionable features of the self- Myinvention consists inlthe novel construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is -3o a central transverse sectional view of my im proved wheel. Fig. 2 is a sectional vi'evi: of 1 3 is a face view of the wheel. Fig. 4 is an er ilargedsectional view of a portion of the Fig. 5 is anenlarged viewinperspectiv'e of the pronged spring-seat.

In carrying my invention into efiect I cast a metal wheel .in a mold having a suitable 40 core and produce thereby a wheel having a hollow or chambered hub A with an opening through the outer wall of the chambere ortion, as seen at a, for the admission of ubricating-oil and openings b b in the ceneel adjacent to one of the side walls of the hub for the passage of the oil from the chamber A to the axle. To give strength to the wheel and prevent the injurious effects of contraction or shrinkage, I

cast the hub A with a scalloped or corrugated outer wall B, as shown in Fig. 3, and with spokes C, which are usually and preferably curved, proceeding from the elevated portions of the scallops to the rim of the wheel.

While the hollow portion or cavity within the hub constitutes an oil-chamber, allowing Specification of Letters Patent. lpplioatlon am March 6,1905. Serial m1. 243,460.

the oil 'to'fl'ow around it, I provide 'a special compartment or cage therein for the recep tion of the waste or Racking 1), usually employed in lubricatingpose I cast the hub with the gratings g g se arated from each other circumfergntia y about the distance of twoscalio' s.

these gratings takes u t 0 oil and overcomes the tendency of the oxes, and for this pur' The waste or packing beingl confined" "etwee'n ,65 atter to fly outwardly under centrifugal force when the wheel is in motion, and the corrugations prevent it from adherin to the inner surface of the outer wall of Elie hub and cause it to splash and be distributed throughout thecharnber and toward the 0 enings b b.=

v orm of the hub produces a certain amount of resiliency that .will not allow the hub tounduly expand in cooling andv relieves the strain produced by the shrinka e of the casting w In wheels of the self-oiling type it has been customary to rovide a hole in the inner side ow hub opposite the oil-inlet oil-valve and spring. I have found this arrangement to be objectionable and expensive,

and accordingly I have dispensed with the hole for the insertion of the valve and spring in this way and with the lug by which such hole is closed and adopt t e expedient of insertingiithe said valve and spring in the oilcavit by passing them through one of the oil-in ets leading to the axle-bearing. The

oil-valve consists of a stem 0, having a rounded head (1, and this head is seated either against a suitable seat formed around the inner edge of the oil-inlet during the casting of the wheel or inand a ainst a seat formed in a may be secured inpothe hol ow of the hub and shrunk into the wall of the casting, the pur ose of the prongs, which are designated i, sing to serve as guides for the head of the valve.

The s ring F seats at its inner 'end in a socket g which is formed with a raised edge or shroud 9 which is cut away at one side, and adjacent tothe cut-away portion of the e cooling afterit has con Thej scalloped or I shroud is formed an inclined guidewayh, ex-

tending toward the hole I).

Instead of the socket above described a nip le-like projection ma be cast integral wit the wheel, over whic the spring passes and rests, being guided thereto by an inclined bered hub with an 011 'guidewav leading to the hole I). The hole 6 or the insertion of the valve and s ring is located close to the the hub to of the valve between the prongs of the guide e. The end ofthe spring is then pushed through the hole 5 and rests on the guide it until its end springs into the socket g at the end of said guide.

at I claim as new, and desire to secure by Letters Patent, is?

1. A self-oiling car-wheel,-having a chambered hub for the reception of lubricating-oil, and a hole leading from said chambered portion of the hub through the axle-bearing wall of the hub,- adjacent to the inner face'of the wheel, there being an oil-inlet through the outer wall of the hub, a valve to close said inlet, a spring bearing against said valve, there ein a spring-seat opposite said inlet With a beve ed or indlined guiding projection formed on the inside of the hub-cavity to facilitate the seating of the sprin 2. A self-oiling car-w eel, having a cham- 'openin in its outer wall, a valve-cage, seated in sai openingand open at its inner end, a valve and valvesfiring Working in said cage, and rojecting t rough its inner end, and means or retaining the inner end of the spring and preventing its lateral displacement.

3. A self-oiling car-wheel having an oil chamber with an oil-inlet through one wall, a valve-guiding cage cast in said wall and projecting into the oil-chamber, a valve having ing at one end against said opposite end against the opposite wall of the oll-chamber, said cage being arranged oppoof the wall of the lengthwise the valve is forced inwardly.

4. A self-oiling car-wheel having an oilchamber with anioil-inlet through the outer Wall of the chamber, a valve-cage cast in the wall of the oil-chamber and extending into the oil-chamber from the oil-inlet and 0 en at its inner end, an inwardly-o ening vaiive a spring bearing against t e valve and seating against the inner wall of, the chamber, said chamber being formed with an openin for the insertion of the valve and spring, sai o ening being located out of alinement with tle axis of the valve-cage. 5. A self-oiling car-wheel having an oilchamber with an oil-inlet through the outer wall of the chamber, a valve-cage cast in the and lunitin g movement of the valve when Wall of the oil-chamber and-extending into the oil-chamber from the oil-inlet and open at its inner end, an inwardl -opening valve and a spring bearing against the valve and seat mg a ainst the inner wall of the cha mber,

said 0 amber being formed with an opening for the insertion of the valve and spring, sai

o ening being located out of alinement with t e axis of the valve-cage, the valve-cage terminating a suflicient distance from the opposite wall of the chamber sertion of the valve and spring into the cage om a point lateral to the axis of the cage.

In testimony whereof I affix my signature in presence of two witnesses.
